Acids are stored in (PET) plastic bottles. Why?
Answers
Answer:
That’s not routine practice for most acids: the stock acids we get are routinely sold and stored in glass. However, it’s not unusual to store working solutions, especially of dilute acids, in plastic containers (usually PE or PP) since they withstand the acids well enough and virtually eliminate the possibility of breakage. HF is of course stored in plastic because it attacks glass.
Solutions of strong bases are preferentially stored in plastic, because bases will also attack glass: not enough to eat their way out of the bottle, but enough to contaminate the solution with silicates, sodium ion, calcium ion, and whatever else the specific glass contains. Also, storing a basic solution is a ground-glass stoppered bottle makes it very likely you’ll find the stopper irretrievably stuck
Explanation:
Answer:
acids store in plastic bottles because plastic is resistant to the action of chemicals but not glass and metals. Hence, plastic bottle are used to store acid and chemical.
